Location: Our office is located in Oxford, England (UK), with hybrid working Job ID: 1820 **We are looking for a Senior Electronics Engineer to join our Reliability Engineering team at the company. In this role, you will be responsible for finding, root-causing, and permanently resolving electronics and control hardware issues on our operational trapped-ion quantum computers, contributing to the team's mission of improving fleet uptime and driving down the operational cost of our commercial and development systems. You'll play an important part in owning the full lifecycle of electrical reliability fixes — from identifying a real-world bottleneck through to standardizing the resulting fix into every future build — working closely with Operations, Science, Manufacturing, and Engineering to keep our quantum systems running reliably and effectively.

In this position, you will work on root-causing, designing, and deploying electronics system design fixes across our fleet of quantum systems, supporting the effective delivery of reliable, development and production hardware . You'll have the prospect to drive system upgrades, standardize control and drive electronics across systems, and build the observability that catches problems before they cause downtime , contributing directly to the success of the Reliability Engineering team . Actively monitor, root-cause, and prioritize electrical, control-system, and drive-electronics issues on live systems based on severity and impact to uptime and performance.

Design, prototype, build, and test electrical fixes — spanning schematic capture, PCB layout,



and board- and system-level test — taking solutions from concept through to permanent integration. Drive electrical workstreams for major fleet-wide upgrades (e.g. control-hardware consolidation, drive-electronics standardization, remote telemetry/monitoring for laser and system health) to reduce variance and downtime across systems.

Retrofitting & deployment: Coordinate directly with Operations and Science teams to schedule, deploy, and retrofit upgrades onto live systems while managing operational constraints, and verify fixes improve system performance, reliability or operability. Feed validated fixes back into engineering documentation, build manifests, and the Engineering Change Request (ECR) process so every improvement is baked into the baseline for all future builds. To be successful, you will need strong foundations in analogue, RF, and mixed-signal electronics design,experience with the Altium PCB toolset, familiarity with RF concepts and confidence working directly onoperational hardware under time pressure.

We're looking for someone who can translate a system-levelreliability problem into a concrete engineering solution, work across Operations, Science, and Engineeringto get it deployed safely, and document it so it sticks. Analogue and mixed-signal electronics: strong practical experience designing and debugging op-amp circuits, low-noise amplifiers, filters, ADC/DAC modules, grounding, shielding and common digital interfaces.

Altium design control and documentation: strong experience managing evolving schematics and PCB designs in Altium, producing clear technical documentation, and establishing effective review, ERC/DRC, release and change-control processes. Fault-finding and electrical integration: able to diagnose power supplies, analogue circuits and control electronics, and develop reliable PCBs, adapters, connectors, breakout cables and harnesses.

Stakeholder engagement and delivery: able to gather requirements, explain technical issues and trade-offs across different disciplines, and take solutions through testing, deployment and documentation.

Bonus:



familiarity with LVDS and FPGA-based control electronics, cryogenic or RF/microwave systems, and Python-based test automation or telemetry.

Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity.
